Elevator chains are essential components in various industrial applications, particularly in vertical lifting systems. These chains must meet high standards for wear resistance and tensile strength to ensure long-term performance and safety. To achieve this, we perform secondary heat treatment on the rollers and bushings. The process begins with carburization, followed by a second heat treatment that enhances surface hardness while maintaining core toughness. This ensures superior crushing strength and durability.
Given their primary use in vertical material lifting, elevator chains require strong structural integrity to prevent loosening. We optimize the machining allowances of all parts to ensure precise fit and assembly. A hydraulic press is used during the assembly process, ensuring reliable and stable connections between chain components.
Our elevator chains are widely used in industries such as cement, mining, grain processing, road construction, and steelworks. They are designed to operate efficiently even in harsh environments where dust and hard particles may be present. Whether it's for conveying materials or elevating heavy loads, our chains deliver consistent performance and reliability.

Crushing equipment refers to machinery used to reduce large rocks into smaller rocks, gravel, or rock dust. It is commonly used in the mining, construction, and recycling industries to break down materials for further processing. Some common types of crushing equipment include jaw crushers, cone crushers, impact crushers, and hammer mills. These machines are designed to handle different types of materials and can be used for primary, secondary, or tertiary crushing. Crushing equipment is essential in the production of aggregates for construction purposes and in the mining industry for the extraction of valuable minerals.
